German magazine TOUR has featured a comprehensive road tyre test, covering many aspects of tyre performance, even including 'real time' wet grip where their human tester donned motorcycle leathers and pushed his specially adapted test bicycle to the limit on each different set of tyres. The complete test can be downloaded here. The Continental GP4000s was a clear winner by performing well in all areas. The test was won in 2007, 2008, 2009 (in 2010 the limited version GP 4000 RS was unbeatable). Not only the German magazines are cocksure! The magazine BICYCLING from the USA announced: “This is not only the best Conti ever but, all things considered, one of the best tires ever made.“ Fast, smart, special The Grand Prix 4000s boasts global appeal as the best all round race bike tyre on the market.

Vectran™ Breaker The innovation in puncture protection. Vectran™ is a multifibred thermoplastic yarn, made of melted Vectra™ Liquid Crystal Polymer. Vectran™ is the only LCP fibre in the world, which is made using a spinning process. Reinforcing and matrix fibres made of Vectran™, are lightweight, extremely durable, have reliable longevity and are five times stronger as steel. With a layer (breaker) of Vectran™ under the tread, the tyre is protected from breakdowns more efficiently than with a Nylon Double Breaker. This is because a single Vectran™ layer is lighter, more flexible and stronger than the two nylon layers.
